Alumina ceramic is an industrial ceramic with high hardness that can only be processed by diamond grinding. It is made of bauxite and can be processed using injection molding, pressing, isostatic pressing, sliding casting, etc., then Pintejin ceramics Let us introduce the properties and characteristics of alumina ceramics. Properties and Characteristics of Alumina Ceramics Using high-purity sub-μm aluminum oxide ultrafine powder, it is possible to produce aluminum oxide high-precision ceramic raw materials with a tensile strength of 700-1000Mpa and a Weber displacement coefficient of 40. However, the impact toughness of such raw materials is extremely low. Generally only 3 ~ 4MPa.m. Therefore, improving the impact toughness of alumina ceramics has Read more

With the continuous development and progress of science and technology, alumina ceramics with superior performance are widely used in various fields due to their own advantages. We know that wear resistance is a very important performance feature of alumina ceramics. What will affect the oxidation resistance? What about the wear resistance of aluminum ceramics? The following is a brief introduction to the performance of alumina ceramics and the influencing factors of wear amount by Pintejin ceramic manufacturers. Alumina Ceramic Plunger Alumina ceramic has good high temperature resistance, high mechanical strength and good conductivity. However, it should be noted that when washing the ceramic, it should be washed with ultrasonic waves, Read more

The principle of extrusion molding: the metal powder can be extruded at a certain temperature (usually in the range of 40-200 °C) after adding a certain amount of organic plasticizer to mix evenly. This method is called “cold extrusion method”. Or “plasticized powder extrusion”. It is generally extruded under normal temperature conditions. The ceramic powder used for extrusion molding must be mixed with water and plasticizer to prepare a billet before it can be used for extrusion molding. Vacuuming during the extrusion process is beneficial to the discharge of air in the blank, so that the green density of the shaped blank can be increased. During the extrusion process of Read more

The temperature difference and time of the high-temperature firing treatment after the alumina ceramic blank is formed have a great influence on the finished product. Therefore, the alumina ceramic ceramics have stricter requirements on the firing temperature in terms of performance and quality. To accurately control the sintering temperature, then we should take corresponding measures. Different alumina ceramics have different sintering temperature requirements, and the sintering temperature is actually related to the content of alumina. Theoretically, the higher the alumina content, the higher the sintering temperature. In fact, this statement is not completely absolute. It is also necessary to observe the composition and proportion of ceramic materials. Generally, when we Read more

But it also has Read more

Ceramic materials are typical hard and brittle materials. Before the mid-to-late 20th century, people thought that zirconia ceramic materials could not be processed or could not be processed, so they could only be processed into the desired shape when making green bodies, and then used directly after firing. The reason for removing the hard and brittle characteristics of the ceramic material itself is mainly due to the lack of machining tools and machining methods at that time. Although people have discovered superhard materials such as diamond and vertical boron nitride that are much harder than ceramic materials, the machining of ceramic materials has only been developed in recent decades. The Read more

At present, the main raw material for the production of special alumina products is industrial alumina, which is an intermediate product of the aluminum smelting industry. Its true density is 3.60g·cm-3, and its mineral composition is γ-Al2O3. Industrial alumina is white powdery material. The chemical composition of general products is shown in the table. When manufacturing special pure products, raw materials with Al2O3 content greater than 99.8% or raw materials prepared from aluminum sulfate and ammonium sulfate should be used. Industrial alumina is difficult to sinter. In order to improve the sintering temperature, the raw materials need to be finely pulverized and pre-sintered, and additives that promote sintering are added. Read more

In the realm of modern electronics, where precision and efficiency reign supreme, the quest for superior materials and manufacturing techniques is unending. Among the myriad of components that constitute the backbone of electronic devices, printed circuit boards (PCBs) stand as fundamental pillars. These intricate platforms serve as the very foundation upon which electronic circuits are built, enabling the seamless flow of electrical signals. In this pursuit of excellence, one innovation has emerged as a cornerstone in the domain of PCB fabrication: the Alumina Multi-Layered Board by Etching. The Alumina Multi-Layered Board (AMLB) represents a pinnacle of engineering ingenuity, combining the remarkable properties of alumina with the intricacy of multi-layered design. Read more

Performance of zirconia ceramics: pure ZrO2 is white, yellow or gray when it contains impurities, and generally contains HfO2. Zirconia ceramics are a new type of ceramics. Because of their excellent physical and chemical properties, zirconia ceramics have not only become a research hotspot in the field of scientific research, but also have been widely used in industrial production.
